A reduced graphene oxide/covalent cobalt porphyrin framework for efficient oxygen reduction reaction

Abstract

A reduced graphene oxide/covalent cobalt porphyrin framework has been synthesized by using pyridine-functionalized reduced graphene oxide (G-dye) as the building block. Due to the unique 3-dimensional architecture and good electronic properties of graphene, as well as the electron accepting ability of the nitrogen atoms in the G-dye, the as-synthesized CoCOF-Py-0.05rGO catalyst exhibits excellent oxygen reduction reaction (ORR) activity with superior long-term stability and methanol tolerance.
